Miniature industrial electromagnetic relays R2N / R3N / R4N - design and technological changes

The offer of Relpol S.A. has been extended by new  electromagnetic relays R2N, R3N, R4N which are modernized versions of the relays R2, R3, R4 still available in the offer.


The new relays are extinguished by a modern design, higher quality and high functionality. They are manufactured  in a modernized technology.


Major changes in the design of the relays:

  • improvement of the functionality of the mechanical indicator - The shape and suspension of the indicator (W) have been changed  – in the new solution it is mounted on an insulation base of the unit of the movable contacts. The changes arising from the different place and manner of the indicator operation provide the appropriate position in the window in the upper side  of the housing irrespectively of the number of operations performed by the relay.
  • application of electronics in the SMD technology   for the additional features L and D - The change of the position of the LED diode and optimization  of the quality and intensity of its light provide certainty that the relay  is in operation status when the LED is on.
  • improvement of the efficiency of the electromagnet - An innovational technology of connecting elements has been introduced in the  electromagnet, which guarantees more  reliable operation of the relay.
  • strengthening of the insulation in the area of the contact plate - An insulation material of the latest generation  has been applied for the manufacture of the contact plate  and the insulation barrier, i.e. polyamide PA66 which differs  from other thermoplastic materials by very good mechanical  and electrical parameters and best thermal properties.

 The R2N, R3N, R4N relays maintain the conformity  of dimensions, raster of the terminals of contacts and coils  and technical data with the respective R2, R3, R4 relays.  They are available with similar additional features.
